FOUNTAIN-PEN.

Specification of Letters Patent.

Application filed April 7, 1914. Serial No; 830,252.

To all whom it may concern y Belt known that I, J AMES MARLBOROUGH, a citizen of the United States, residlngat Topsfield, in the county of Essexand State 3 of Massachusetts, have invented new and useful Improvements in Fountain-Pens, of which the following is a specification.

The invention relates to fountain pens, and has for an object to provide a fountain pen of a simple construction and which is so arranged and constructed that it will ,not leak when carried in the pocket and When not in use.

k The invention contemplates, amongother features, the provision of a fountain pen having suitable means within the control of the user'whereby the supply of ink to the nib can be shut OK when the fountain pen is not in use and carried in the pocket and whereby such supply of ink to the nib will be uninterrupted when the pen is in use.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a perspective view of the pen; Fig. 2 is a fragmentary vertical longitudinal sectional view; Fig. 3 is a vertical transverse sectional view; Fig. 4 is a perspective view of the valve; and Fig. 5 is a view looking at the under side of the slide. Fig. 6 is a fragmentary plan view of the structure shown in Fig. 1, with the slide member removed.

Referring more particularly to the views, I provide a pen 10 consisting, more particularly, of a barrel 11 and a nib-supporting member 12 adapted for threaded engagement with the barrel 11 and carrying the usual nib 18. The nib-supporting member 12 is provided with a longitudinal passage 14, through which the ink isadapted to flow in passing from the barrel 11 to the nib 13. Mounted to turn in the nib -supporting member 12 is a frusto-conical valve 15 provided with 'a horizontal passage 16 and which, by turning the valve 15 in the nibsupporting member 12. can be moved into or out of registration with the passage 14, said valve 15 being so arranged asto interrupt the passage 14 when it is desired to cut oil the supply of ink from the barrel to the nib.

The nib-supporting member 12 is provided 5 with a recess 17 closed at one end and terminating at the other end adjacent that portion of the nib-supporting member which is adapted for threaded engagement with the barrel 11. Mounted to slide in the saidrecess is a slide member 18, the saidslide member preferably having its sides 19 beveled to conform to oppositely inclined walls 20 of the recess 17 so that when the slide member 18 is arranged in the recess the same cannot be removed except by sliding it out 0f the open end of the recess. A slot 21 is formed in the under side of the slide member 18 and is adapted to receive therein a bead 22 formed on a stem 23 of the valve 15 so that in moving the slide member 18 for- .wardly andbackwardly in the recess 17 rotation will be imparted to the valve 13 to move the passage 16 into or out of registration with the passage 14 in the nib-supporting member 12. A bead 24 is preferably formed at the forward end of the barrel 11 and when the nib-supporting member 12 is threadedly engaged with the barrel 11, the said bead will constitute a stop member to limit the sliding movement of the slide member 18 in the recess 17 so that, in order to remove the slide member 18 from the recess it will be first necessary to unscrew the nibsupporting member 12 from the barrel 11. Now it will be apparent that when the slide member 18 is moved forwardly in the recess Patented Mar. 2, 191 5.

it will impart rotation to thevalve 15 to register the passage 16 with the passage 14 so that the ink can flow from the barrel to the nib, whereas when the slide member is retreated in the recess the valve will be rotated in the opposite direction to move the passage 16 out of registration with the passage 14. thus cutting off the'su'p lv ofink from the barrel to the nib. In order to prevent m stakes bv the user. the letters S and 0 indicating. respectively, Stopped and Open. are stam ed or otherwise formed in the floor or bottom of the recess 17 as shown so that when the letter S is uncovered the slide member will be in its rearmost position, thus through the medium of the valve stopp ng the flow of ink from the barrel to the nib. whereas when the sl de is in itsforward position the letter S will be covered and the letter O uncovered and in position to indicate that the valve is in a position to register the passages 14 and 16 so that the ink can flow from the bar el to the nib.

The slide member 18 is preferably made of resilient sheet metal or the like so that in initially placing the samein the recess 17 the same is sprung into the recess and in order to insure the engagement oftheslide' member With the valve so that the same can be relatively operated and it will beapparent that when the slide member has once however, wouldjlbe impossiblein view, of the beveled sides of the slide f nember and the fact that the bead 1220f the valve extends 1 .into the transverse slot 21 in the under side ib'een sprung intothe recess it will bealmost impossible to conveniently remove the same 7 unless the slide member is slid" outwardly through the open end of therecess. This,

Of-the slidememberj The bead :24 on the forward end of the barrel however, will tend toflimitithe sliding movement of the slide member in therecess, as will be readily understood by'i're'ferr ng to the views Having thus described my invention, I
